What I'm trying to find out is if an hdd platter degrades over time, if I take an hdd out of the comp, stick it in an anti static bag then leave it in a drawer, then in 20-30 yrs take it out of the drawer plug it into a comp providing it spins up and sata still exists , will the data be in tact as it was at the time of storing it or does it degrade some how?
